Chang’e 4 Shields Moon

New research from China's Chang’e 4 lunar lander shows Earth's magnetic field extends farther into space, shielding the Moon from galactic cosmic rays.
The study, published in Science Advances, describes a cavity in space where cosmic rays are deflected.
Robert Wimmer-Schweingruber, co-author, expressed surprise at the results.
Experts say understanding this radiation distribution could inform future lunar missions, improving astronaut safety by allowing planning around the Moon's magnetic protection.

Chang’e 6 Discovers Ions

A Chinese-led research team detected negative hydrogen ions on the Moon's surface with the Chang'e 6 lander and the NILS detector.
They recorded six energy signatures over two days, the first direct measurement of such ions on another celestial body.
The findings could influence water formation and the Moon's thin atmosphere, while offering a framework for studying other airless bodies.
